染色体重排可导致杂种不亲和性的快速进化。罗伯逊融合，特别是那些与monobrachial同源性，可以驱动最近分歧类群之间的生殖隔离。岩沙袋鼠的近期辐射是研究罗伯逊融合在物种形成中作用的一个重要模型。在这里，我们追求这一目标，使用广泛的抽样人口和基因组的Petrogale从澳大利亚东北部。与以前使用线粒体DNA或核微卫星位点的评估相反，基因组数据能够分离最密切相关的物种并解决其分歧历史。系统发育和群体遗传分析表明，两个物种之间的渐渗不同的一个单一的罗伯逊融合。根据现有的数据，也有证据表明，两个物种之间的基因渗入，共享复杂的染色体重排。然而，其余的结果显示在物种对之间没有一致的渐渗特征，并且在明显的情况下，表明总体上一般低的渐渗。与常染色体位点相比，X连锁位点具有较高的趋异性，这表明基因进化在染色体变化中产生生殖隔离的潜在作用。我们的研究结果强调了基因组规模的数据在评估罗伯逊融合和结构变异在分歧，物种形成和分子进化模式中的作用的价值。
Chromosome rearrangements can result in the rapid evolution of hybrid incompatibilities. Robertsonian fusions, particularly those with monobrachial homology, can drive reproductive isolation amongst recently diverged taxa. The recent radiation of rock-wallabies (genus Petrogale) is an important model to explore the role of Robertsonian fusions in speciation. Here, we pursue that goal using an extensive sampling of populations and genomes of Petrogale from north-eastern Australia. In contrast to previous assessments using mitochondrial DNA or nuclear microsatellite loci, genomic data are able to separate the most closely related species and to resolve their divergence histories. Both phylogenetic and population genetic analyses indicate introgression between two species that differ by a single Robertsonian fusion. Based on the available data, there is also evidence for introgression between two species which share complex chromosomal rearrangements. However, the remaining results show no consistent signature of introgression amongst species pairs and where evident, indicate generally low introgression overall. X-linked loci have elevated divergence compared with autosomal loci indicating a potential role for genic evolution to produce reproductive isolation in concert with chromosome change. Our results highlight the value of genome scale data in evaluating the role of Robertsonian fusions and structural variation in divergence, speciation, and patterns of molecular evolution.
